COMBINE D AXLE-NUT AND Ol L-CAP FOR WHEELS.

SPECIFICATION forming part of Letters Patent No. 702,612, dated June 17,1902.

Application filed July 29,1901.

To wZZ whom it may concern.-

Be it knownthat I, ARTHUR CHARLES A'r- KIN, coach-builder,asubject of His Majesty the King of the United Kingdom of Great Britain and Ireland, residing at the city of Auckland, in the Provincial District of Auckland and Colony of New Zealand, have invented a certain new and useful Combined Axle-Nut and Oil-Cap for Wheels of Vehicles and such Like, of which-the following is a specification.

This invention is intended to supply the place of either an axle-nut .or oil-cap and nut and to provide vthe means of keeping th'earm of axle constantly oiled.

It consists of the combination in one ofthe axle-nut and oil-cap at present used on the outer ends of lubricating-axles of vehicles and" of an oil-conductor in the axle to carry the'oil of the combined axle-nut and oil-cap thereon.

The combined axle-nut and oil-cap A, with the oil-reservoir B within it, is screwed onto the end of the axle-arm G, so that the latter will project into the reservoir. The arm G is bored to form a lubricant conductor or feeder C, leading from the reservoir Bto the groove D on the under side of the axle-arm, which distributes the oil along thearm. The inner end of the cap A is provided with an annular flange A, which is adapted to surround the washer F, the latter beinginterposed between the box E and cap A. The box E keeps the oil on the arm, while the washer F engages with the flange A and keeps the combined nut and cap from rattling. A hole countersunk in axle-arm at D can'take the place of the groove, if preferred.

In the ordinary axles thewheel requires to be taken off and grease placed on the axlearm. Then the wheel and'nut are replaced, while in the majority of lubricating-axles nuts nut.

Serial No. 70,152. (No model.)

are employed on the front of the axle-arm to keep the wheel on and the cap forthe oil screwed on at the front of the box-covering The combined axle-nut and oil-cap in itself keeps the wheel on and contains the oil necshape and constructed of any suitable material. It is suitable 'for axles of any form of vehiclesperambulator's, cycles, and agricultural 'implementsand can-be used on light vehicles on which lubricating-axles have,

never previously been used, no oil-axle in the pasthaving been found suitable.

Havingfu'lly described my invention, what Idesire to claim and secure by Letters Patent 1s- In a lubricating-axle, an axle-arm having a bore forming a feed-passage for the lubricant, I

said passage extending from the outer end of said arm downwardly at an inclination and terminating at its inner end in a groove on the under side of the said arm,said passage having its outer end arranged eccentrically with respect to the center of the axle-arm, an integral axle-nut andan oil-cap, said oil-cap forming a reservoir for the lubricant, said axlenut adapted to be mounted upon the axle-arm so that the latter with the outer end of the feed-passage will extend through the nut and into the reservoir without engaging the walls of the latter, a washer interposed between the nut and arm, there being a flange integral with the 'nut and cap surrounding and engaging the washer to prevent the former from rattling, substantially as herein shown and described. r
